The PCM provides a 5volt reference voltage to the Air-con Pressure Transducer(APT) and Power Steering Pressure Sensor(PSPS). The PCM monitors reference voltage deviation from the power supply circuit of the APT and PSPS.
PCM sets DTC P06A5 if the PCM detects reference voltage of APT is Higher than threshold value.
